If another average life is desired, these ratings must be modified by factors as follows: 00 Hours Hours Hours Hours Hours Hours Hours Hours Hours Hours Hours Hours Hours Hours -.68 Correct operating tension is an important factor in the satisfactory performance and life of any V-belt or chain drive. As V-belts wear they seat themselves deeper in the sheave grooves. This seating, along with belt stretch, lessens the initial tension. The result is slippage and loss in horsepower capacity unless some form of take up is used to restore and maintain original tension. As chains wear they elongate, which results in sway or slap and increased vibration. This puts undue shock into the drive and increases bearing wear. Both V-belt and chain drives wear at an increased rate if allowed to run with insufficient tension. Adjustment of center distance is the best method of maintaining proper tension. In cases of fixed centers, BROWNING Drive Tighteners and Idlers provide the necessary means of take up. The BROWNING Drive Tighteners also provide a means of obtaining extra belt or chain wrap frequently needed for extremely high ratios, multiple shaft or serpentine drives. Careful consideration must be given to the following when using idlers: BROWNING DRIVE TIGHTENERS AND IDLERS. Too much tension in a drive causes excessive belt, chain and bearing wear. 2. Too little tension in a drive allows belt slippage or chain vibration, resulting in loss of power and additional wear.. All idlers should be used on the slack side of the drive. 4. V-belt drive idlers should be used on the inside of the belt. Allowance should be made for horsepower loss due to the reduced arc of contact.. Where necessary to use V-belt drive idlers on the outside of the belt, the reverse bending will reduce belt life. 6. Flat face pulley idlers can be used on either inside or outside of the belt.. Sprocket idlers should be used on the outside of chain drives, and with at least three teeth engaged in the chain. 8. Idlers used on the inside of a drive should be located approximately / of the center distance from the large sheave, pulley or sprocket.. Idlers used on the outside of a drive should be located approximately / of the center distance from the small sheave, pulley or sprocket. I-

HUB BUSHING BORE RANGE MINIMUM NUMBER OF TEETH ON ROLLER CHAIN SPROCKETS AND GEARS CHAIN SIZE - TYPE A SPROCKETS PITCH - CHANGE GEARS AAH - G G AAH - H H AAH - Q Q When a particular phase relationship is required between two parts of a machine, the Angle Adjusting Hub provides quick, accurate and positive phase adjustment. Without the Angle Adjusting Hub, phase relationship of parts requires extremely accurate machining of components as one tooth of a sprocket or gear is usually too coarse an adjustment. The desired component is simply bolted to the Angle Adjusting Hub and by use of the two adjusting screws, infinite adjustment can be made throughout the 24 range of the Hub. Once adjusted the Hub cannot slip out of adjustment because, when both are tightened, the adjusting screws act against each other like jam nuts. Angle Adjusting Hubs are machined for Browning Split Taper Bushings so that the complete bore range of the bushings shown is available in / 6 increments from STOCK.. Eliminate extended deliveries on "Key -wayed on Centerline" items. 2. Compensate for Chain and Tooth wear in alignment applications.. Ideal for timing or synchronizing applications. 4. Bore Range of / 8" - 2 / 6",.8 through / 8 Spline and 4 mm through 60 mm bore available OFF THE SHELF.. Adjust quickly and easily. I-8
